Patent number: 7166479Abstract: A monolithically formed ferromagnetic thin-film memory is disclosed that has local shielding on at least two sides of selected magnetic storage elements. The local shielding preferably extends along the back and side surfaces of a word line and/or digital lines of a conventional magnetic memory. In this configuration, the local shielding not only may help reduce externally generated EMI, internally generated cross-talk and other unwanted fields in the magnetic bit region, but may also help enhance the desired magnetic fields in the bit region.Type: GrantFiled: November 19, 2004Date of Patent: January 23, 2007Assignee: Micron Technology, Inc.Inventors: Theodore Zhu, Jeffrey S.

Patent number: 6048739Abstract: A high density magnetic memory device and method of manufacture therefor, wherein the magnetic bit region is provided after selected higher temperature processing steps are performed. Illustrative higher temperature processing steps include those that are performed above for example 400.degree. C., any may include contact and via plug processing. The present invention may allow, for example, contact and via plug processing to be used to form magnetic RAM devices. As indicated above, contact and/or via plug processing typically allows the size of the contacts and vias to be reduced, and the packing density of the resulting memory device to be increased.Type: GrantFiled: December 18, 1997Date of Patent: April 11, 2000Assignee: Honeywell Inc.Inventors: Allan T.
